I'm not sure you'd need to bring your own water, the sulfuric acid is produced in the upper atmosphere when sunlight splits carbon dioxide into carbon monoxide and oxygen which then react with water vapour and sulphur dioxide. We could harvest that water vapour and CO2 to produce oxygen, water, and rocket fuel. We've got lots of experience with sulfuric acid and resistant materials are rather common place plastics (including teflon) and stainless steel. I have no idea why there hasn't been more of an effort to get a flying robotic probe to Venus. I think it would be mindblowing to have high res pictures and video of the upper atmosphere with a bright sun over head and an endless sea of clouds.
